An episode on TruckU | on SPEED
they have the guys removing the entire 6.7L exhaust system and going with aftermarket non DEF/DPF exhaust and a tuner. So it can be done. However, like the previous F350/250 versions, when you crank up the tuner wick, the tranny and rear end then tend to go out early.
Sorry have to disagree with you. Now what I'm going to say has to be within reason. A mild tune for safe towing would yield more power. Now more power= better mileage which = less emissions which equals less regens.
People says tuned diesels are ruining the environment, and yes the guys that go nuts and blowing smoke everywhere are wasting energy, but the ones that tune properly that are increasing there mileage sometimes by as much as 50% are doing more good then all the emissions crap on these new trucks. Better mileage equals less emissions.
